stripDirs('foo/bar/baz', 999); //=> 'baz'

API
const stripDirs = require('strip-dirs');
stripDirs(path, count [, option])
path: string (A relative path)
count: integer (>= 0)
option: Object
Return: string
It removes directory components from the beginning of the path by count.
const stripDirs = require('strip-dirs');
stripDirs('foo/bar', 1); //=> 'bar'
stripDirs('foo/bar/baz', 2); //=> 'bar'
stripDirs('foo/././/bar/./', 1); //=> 'bar'
stripDirs('foo/bar', 0); //=> 'foo/bar'
stripDirs('/foo/bar', 1) // throw an error because the path is an absolute path
If you want to remove all directory components certainly, use path.basename instead of this module.
option.disallowOverflow
Type: boolean
Default: false
By default, it keeps the last path component when path components are fewer than the count.
If this option is enabled, it throws an error in this situation.
stripDirs('foo/bar/baz', 9999); //=> 'baz'
stripDirs('foo/bar/baz', 9999, {disallowOverflow: true}); // throws an range error
